Master Data Configuration
Realtime Data communication works with Realtime Keys. The first thing you need to do if you want to enable realtime data communication on an object is to create a realtime key that is linked to a single get method from that object. This single get method will be used to notify a view with the new, deleted or updated changes from a specific record.
You can configure these realtime keys on the top left corner of the screen.
This will open a new screen where you can manage all the realtime keys that exist in the framework.
When you create a realtime key, a GUID will be generated. This GUID is used to notify a view that a specific record has been modified. You can also give the realtime key a label and you need to link a single get method to the realtime key.
In the image above, you can see that we've created a realtime key for an Employee object. When an employee is deleted, created or updated, the single get method 'Get Employee' will be invoked to retrieve the new data to be shown on a view.
Note
Only methods of type 'SingleRead' will be shown in the method setting configuration. Make sure that you have set this type on the method you want to link to your realtime key.
